What does modeling, singing, dancing, and being an actress all have in common? Trying to get people to look at you, to put yourself up on a pedestal. I'm not exactly the first person to discover these are stereotypical bimbo professions.
It likely involves something Freudian in nature where the dumber people are, the more they're mostly driven by animal instincts like reproduction, and if you can put yourself up on a pedestal like you're something to be worshiped, it's a way to try and get the "alpha-males" to fight over you, which aids in the natural selection process.
Nobody has complete free will, but some people have more than others. The girls in these pictures, you can just look at their eyes and tell there is nothing going on upstairs, and in that case, they function basically as biological robots and are more prone to stereotypical, predictable, deterministic behavior.
If you don't tell them their interests are vapid, vain, and horrible, and instead worship them for their bimbo behavior, you're subsidizing the creation of monsters. This is why western women are so bad compared to many other countries. Instead of saying, hey, you gotta stop doing this shit, people reward them for it.
